Serial port, parallel port, game port, Apple Desktop Bus, PS/2 port, and FireWire (IEEE 1394) Universal Serial Bus ( USB) is an industry standard that allows data exchange and delivery of power between many types of electronics. It specifies its architecture, in particular its physical interface, and communication protocols for data transfer ...
USB Key Mode: The user must insert a USB device that contains a startup key into the computer to be able to boot the protected OS. Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment. BitLocker does not support smart cards for pre-boot authentication.

Two experimental, unofficial solutions are available for DOS. The loadable USBEXFAT driver requires Panasonic's USB stack for DOS and only works with USB storage devices; the open-source EXFAT executable is an exFAT file-system reader and requires the HX DOS extender to work. [73]
The phenomenon of disk failure is not limited only to drives, but also applies to other types of magnetic media. In the late 1990s, Iomega's 100-megabyte Zip disks used in Zip drives were affected by the click of death, called so because the drives endlessly clicked when accessed, indicating the impending failure. 3.5-inch floppy disks can also fall victim to disk failure.
The format used in Microsoft Standalone Disk BASIC's 8-bit file system precursor was not supported by QDOS. By August 1980, QDOS had been renamed 86-DOS . [ 20 ] Starting with 86-DOS 0.42 , the size and layout of directory entries was changed from 16 bytes to 32 bytes [ 21 ] in order to add a file date stamp [ 21 ] and increase the theoretical ...
Disk partitioning or disk slicing [1] is the creation of one or more regions on secondary storage, so that each region can be managed separately. [2] These regions are called partitions. It is typically the first step of preparing a newly installed disk after a partitioning scheme is chosen for the new disk before any file system is created.
An operating system ( OS) is system software that manages computer hardware and software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and ...
Examples of software that can be used on a bootable rescue disk include the Trend Micro Rescue Disk, [171] Kaspersky Rescue Disk, [172] and Comodo Rescue Disk. [173] Most of the rescue disk software can also be installed onto a USB storage device that is bootable on newer computers.
